Let me know the reason, there is a good lad or lassie

By far the better (and more honest) course is either to humbly acknowledge the mistake or set out why you said what you did in the first place.

We can't always do that in the RPG forums, though. It would be quite inappropriate to interrupt a game to make a post apologizing for forgetting to eliminate your signature or mistaking where another character was supposed to be.

Edited to add that you could actually post such apologies in the Discussion thread. Silly me.
